Abstract

The invention discloses an intravascular thrombus and embolus resectoscope. The technique problem to be solved is that while thrombus and embolus are taken out, the distal end of a blood vessel cavity is protected. The intravascular thrombus and embolus resectoscope is provided with a thrombus resectoscope. The thrombus resectoscope comprises a basket with netting on top which shows shrinkage or releasing state and is arranged on the distal end of the thrombus resectoscope. A guide bar is connected with the basket with netting at the same axis; the distal end of the guide bar is connected with a soft guide wire head; when the basket with netting on top shows shrinkage or releasing state, the whole thrombus resectoscope is arranged in a delivery pipeline which is arranged in a recovery pipeline and can extends towards the distal end along the recovery pipeline. Compared with the existing technique, the blood stream of the blood vessel can continuously flow in the process of the capturing, winding, and extraction of the thrombus; the invention does not interface the blood supplying of the normal brain issue and protects the distal end of the cavity of the blood vessel; all gore or thrombus chips generated from the extraction process of the thrombus and embolus can be taken out.

Description

technical field

[0001] The invention relates to a medical device, in particular to a medical device for vascular interventional treatment.

[0002] A new type of intravascular thrombus and embolism resection device used in clinical blood vessels of various calibers, including small blood vessels, especially for cerebrovascular embolism diseases. The patency of the blood vessels and the blood supply of the blood vessels are restored; while the thrombus and embolism are removed, the distal end of the blood vessel lumen is protected, so that all blood clots or thrombus fragments generated during the removal of the thrombus and embolism can be removed. Therefore, it is a device for removing thrombus and embolism in tiny blood vessels in the body with distal protection, especially in cerebral blood vessels. Background technique

[0003] Small vessel thrombosis is a common clinical disease. Particularly striking are thrombosis of small blood vessels in the brain and cerebral emb...
